G is the hub-shell of the wheel-rim H, to which it is attached by means of wires h h, as usual. To one end of the shell G is firmly fixed an end piece or disk I, which is preferably forced into the end of the hub-shell and secured by a key or feather, so as to become practically a part of said hub-shell, as shown in Fig. 2. The end piece I has an inwardlyprojecting sleeve 1, surrounding loosely the shaft A, and to such hollow hub I is firmly secured in a suitable manner a bevel-gear I", the teeth of which mesh into the teeth of the intermediate gears D D, as shown in Fig. 2. The gear I thus becomes practically a part of the hub-shell Gr. On the outside of the end piece I is an annular recess 1 in which are contained a series of anti-friction balls t i, adapted to roll against a conical projection K, which forms a part of the ball-case K, which latter is secured to the lower end of one side of the forked frame L, as shown in Figs. 2, 7, 8, and 9. By this arrangement a three-point-contact anti-friction device is established betweenthe end piece land theinner end of the ball-case K, one of such contacts being established between the conical projection K and the anti-friction balls 2' and the other two between said balls and the bottom and side of the cup-shaped recess I as shown in Fig. 2.

The ball-case K has in its outer end an annular cup-shaped recess K" in which are contained a series of anti-friction balls 7c. (Shown in Fig. 2.)

a is a screw-threaded portion of the axle A inside of the place where one of the cranks B is secured, and on such screw-threaded portion is screwed a cone-nut k, the conical portion of which serves as a bearing-surface for the balls 70 1c, and by this arrangement a three-point-contact anti-frictional device is established between the ball-case K and the adjustable cone-nut k, one of such contacts being established between the balls k 70 and the conical surface of the cone-nut 7c and the other two between said balls and the bottom and side of the annular recess K in the ballcase K, as shown For the purpose of securing the cone-nut 7c in place upon the axle A after being adjusted in position thereon, I provide its outer face with a series of perforations k" 70', adapted to receive the end of a locking-plate k secured to the crank B by means of a screw k or equivalent device. The opposite end of the hub-shell G is provided with an internal screw-thread g,into which is adj ustably secured the screwthreaded soft-metal end piece M, to the central part of which is preferably attached the annular, disk M, as shown in Fig. 2.

end piece M. is preferably shrunk while The heated on the center disk M, which is hardened for the purpose of making such center piece hardened and of standard size and enabling the outer soft-metal end piece M to be afterward screw-threaded and tilted to the internal screw-thread g of the wheel-hub G.

The parts M M may, however, be made in one single piece; but it is more advantageous to make them in two parts secured together as above specified. The disk M has in its outer end an annular recess M", adapted to contain the anti-friction balls m m, as shown in Fig. 2.

N is the ball-case secured to one of the lower ends of the forked frame L, which ballcase has made in one piece with it an inwardly-projecting sleeve N, to which is firmly secured in a suitable manner a bevel gear 0, the teeth of which mesh in the teeth of the intermediate gears D D, as shown in Fig. 2. The sleeve N is also provided witha cone-bearing surface i by which and the annular recess-M a three-point-contact antifrict-ion bearing device is obtained, one of such bearing-contacts being established between the balls m 'mand the other two between said balls and the bottom and side of the annular recess l\ in the center disk M, as shown in Fig. 2.

The ball-case N has in its outer end an annular recess N adapted to contain a series of anti-frictional balls at n, as shown in Fig. 2. On a screw-threaded portion a." of the axle A is adjustably screwed the cone-nutP,which serves as a bearing-surface for the balls or n, and by this arrangement a three-point contact is established between the ball-case N, the cone-nut P, and the balls n it, one of such contacts being established between the conenut P and the balls at "n. and the other two between said balls and the bottom and side of the annular recess N as shown in Fig. 2.

The cone-nut P has on its outer face a series of recesses 11 p, into either one of which is securedthe inner end of a locking-platep, adjustably secured to the crank B by means of a set-screw p" or equivalent device.

By the construction of the wheel-hub and its component parts, as above described, great anti-friction results are obtained, and the wheel can be driven with a minimum of frictional resistance. This result is attained by the cones formed with the screw-nuts E, gears D, ball-case K ,ball-case N, and screw-nuts k and P, for by these cones We reduce the surface contact with ihe balls, provide an improved three-point-contact bearing, and avoid the grinding action which results from the presence of rounded convexed bearing-surfaces which form seats for the balls, as heretofore in this type of epicycle-gear mechanism for velocipedes. It will of course be read ily understood that when the axle A is'rotated it causes an increased rotary motion to be imparted to the hub G and its wheel in the same direction, as is common in multiple-geared velocipedes.

- is detached from the wheel-hub G, the axle and the gears D D 0 may be drawn out of the hub-shell, thus enabling any desired adj ustment or repairs of such parts to be made.

In adjusting the gears and ball-bearings the adjustable hub end M M is screwed in out of s the way and the axle cone-nuts screwed up until the gears mesh properly, after which the said cone-nuts are locked in place by the projections 10 k on the cranks, as hereinbefore mentioned. The adj ustablehub end MM is then unscrewed until the hub is made to fit properly on the ball-cases and their anti-friction balls, after which the said adjustable hub end is secured in place to the wheel-hub G by means of a toothed locking-piece G, secured, preferably, by means of a screw or other equivalent device to the wheel-hub and having its teeth interlocking in a toothed surface M as shown in Fig. 1.

The ball-cases K N have each two or more tenons T T, having squared ends and intervening square bottom spaces 25 adapted to fit in corresponding square-ended spaces and tenons L Z in the end of the forked frame L, and are secured together by means of a bolt L. The object of this form of jointis to hold the ball-cases strictly in line with the axle and to keep them in truth while operating the wheel.

Having thus fully described the nature, construction, and operation of our invention, we wish to secure by Letters Patent, and claim- 1.
